RESUMO

Regarding scarce capacities an early detection consultation (EDC) was established to discriminate patients in an outpatient setting with inflammatory from non-inflammatory rheumatic diseases. A total of 500 patients suspected of having a rheumatic disease received an appointment within 2 weeks. They were interviewed with the help of a digital questionnaire (RhePort), briefly physically examined followed by a determination of CRP. The questionnaire answers were scored using an algorithm within RhePort (from 0 = non-inflammatory to 4 = highly probably inflammatory). Likewise, after completion of the EDC, the rheumatologists scored the overall assessment. The RhePort score and EDC score were compared with the "true" diagnosis made in a detailed second examination after an average of 10 weeks. In 490 evaluable patients 133 inflammatory (27%) and 357 noninflammatory rheumatic diseases (73%) were diagnosed. A classification based solely on the RhePort questionnaire (score > 1) identified 103 out of 129 as inflammatory (sens. 80%) and 125 out of 355 as non-inflammatory (spec. 35%) resulting in an AUC of 0.62 after ROC analysis. With a score > 1, the rheumatological assessment after EDC classified 130 out of 133 patients as inflammatory (sensitivity 98%) and 261 out of 357 as non-inflammatory (specificity 73%). The combined EDC can decisively increase the sensitivity and specificity compared to an "automated" survey by means of a digital questionnaire alone. In addition to the early identification and treatment of inflammatory patients, rapid identification of patients who are not in need of rheumatological treatment can create capacities for care.

RESUMO

OBJECTIVE: To examine the relationship of fear of fear and broad dimensions of psychopathology in panic disorder with agoraphobia over the course of cognitive behavioural therapy in Japan. METHODS: A total of 177 Japanese patients with panic disorder with agoraphobia were treated with group cognitive behavioural therapy between 2001 and 2015. We examined associations between the change scores in Agoraphobic Cognitions Questionnaire or Body Sensations Questionnaire and the changes in subscales of Symptom Checklist-90 Revised during cognitive behavioural therapy controlling the change in panic disorder severity using multiple regression analysis. RESULTS: Reduction in Agoraphobic Cognitions Questionnaire score was related to a decrease in all Symptom Checklist-90 Revised (SCL-90-R) subscale scores. Reduction in Body Sensations Questionnaire score was associated with a decrease in anxiety. Reduction in Panic Disorder Severity Scale score was not related to any SCL-90-R subscale changes. CONCLUSIONS: Changes in fear of fear, especially maladaptive cognitions, may predict broad dimensions of psychopathology reductions in patients of panic disorder with agoraphobia over the course of cognitive behavioural therapy. For the sake of improving a broader range of psychiatric symptoms in patients of panic disorder with agoraphobia, more attention to maladaptive cognition changes during cognitive behavioural therapy is warranted.

RESUMO

OBJECTIVES: To investigate whether reproducibility of gray matter volumetry is influenced by parameter settings for VBM 8 using Diffeomorphic Anatomical Registration Through Exponentiated Lie Algebra (DARTEL) with region-of-interest (ROI) analyses. METHODS: We prepared three-dimensional T1-weighted magnetic resonance images (3D-T1WIs) of 21 healthy subjects. All subjects were imaged with each of five MRI systems. Voxel-based morphometry 8 (VBM 8) and WFU PickAtlas software were used for gray matter volumetry. The bilateral ROI labels used were those provided as default settings with the software: Frontal Lobe, Hippocampus, Occipital Lobe, Orbital Gyrus, Parietal Lobe, Putamen, and Temporal Lobe. All 3D-T1WIs were segmented to gray matter with six parameters of VBM 8, with each parameter having between three and eight selectable levels. Reproducibility was evaluated as the standard deviation (mm³) of measured values for the five MRI systems. RESULTS: Reproducibility was influenced by 'Bias regularization (BiasR)', 'Bias FWHM', and 'De-noising filter' settings, but not by 'MRF weighting', 'Sampling distance', or 'Warping regularization' settings. Reproducibility in BiasR was influenced by ROI. Superior reproducibility was observed in Frontal Lobe with the BiasR1 setting, and in Hippocampus, Parietal Lobe, and Putamen with the BiasR3*, BiasR1, and BiasR5 settings, respectively. CONCLUSION: Reproducibility of gray matter volumetry was influenced by parameter settings in VBM 8 using DARTEL and ROI. In multi-center studies, the use of appropriate settings in VBM 8 with DARTEL results in reduced scanner effect.

RESUMO

Workshops are an important part of the IFPA annual meeting as they allow for discussion of specialized topics. At IFPA meeting 2012 there were twelve themed workshops, five of which are summarized in this report. These workshops related to various aspects of placental biology but collectively covered areas of clinical research and pregnancy disorders: 1) trophoblast deportation; 2) gestational trophoblastic disease; 3) placental insufficiency and fetal growth restriction; 4) trophoblast overinvasion and accreta-related pathologies; 5) placental thrombosis and fibrinolysis.

RESUMO

BACKGROUND: Gestational trophoblastic diseases (GTDs) are related to trophoblasts, and human chorionic gonadotropin (hCG) is secreted by GTDs as well as normal placentas. However, the asparagine-linked sugar chains on hCG contain abnormal biantennary structures in invasive mole and choriocarcinoma, but not normal pregnancy or hydatidiform mole. N-acetylglucosaminyltransferase-IV (GnT-IV) catalyses ß1,4-N-acetylglucosamine branching on asparagine-linked oligosaccharides, which are consistent with the abnormal sugar chain structures on hCG. METHODS: We investigated GnT-IVa expression in GTDs and placentas by immunohistochemistry, western blot, and RT-PCR. We assessed the effects of GnT-IVa knockdown in choriocarcinoma cells in vitro and in vivo. RESULTS: The GnT-IVa was highly expressed in trophoblasts of invasive mole and choriocarcinoma, and moderately in extravillous trophoblasts during the first trimester, but not in hydatidiform mole or other normal trophoblasts. The GnT-IVa knockdown in choriocarcinoma cells significantly reduced migration and invasive capacities, and suppressed cellular adhesion to extracellular matrix proteins. The extent of ß1,4-N-acetylglucosamine branching on ß1 integrin was greatly reduced by GnT-IVa knockdown, although the expression of ß1 integrin was not changed. In vivo studies further demonstrated that GnT-IVa knockdown suppressed tumour engraftment and growth. CONCLUSION: These findings suggest that GnT-IVa is involved in regulating invasion of choriocarcinoma through modifications of the oligosaccharide chains of ß1 integrin.

RESUMO

The pathogenesis of placental mesenchymal dysplasia (PMD) remains unclear. This report presents a case of PMD with a female fetus complicated with intrauterine growth restriction (IUGR). The ultrasound findings were similar to molar pregnancies, but PMD was suspected based on the presence of low ß-hCG levels and a normal karyotype. After delivery, pathological examination of the placenta showed dilated villi and thick-walled vessels lacking trophoblast proliferation, which thus led to a diagnosis of PMD. The VEGF-D (Xp22.31) mRNA expression was found to have increased in the abnormal villi. Whether this is an incidental or X-linked gene specific event in, IUGR complicated, PMD pathogenesis warrants further investigation of VEGF-D expression in PMD.

RESUMO

OBJECTIVES: The purpose of this study was to clarify the clinical outcome of patients with stage IA or more advanced epithelial ovarian cancer (EOC) treated with fertility-sparing surgery (FSS). METHODS: After a central pathological review and search of the medical records from multiple institutions, a total of 60 stage I EOC patients treated with FSS were retrospectively evaluated in the current study. RESULTS: The median age was 30 years (range: 12-40 years). The median follow-up time was 54.7 months (range: 4.8-243.8 months). The stage was IA in 30, IB in one, and IC in 29 patients. Fifty-two patients were alive without relapse and 8 patient experienced recurrences {IA, 2; IB, 1; IC(surface involvement), 1; and IC(positive cytology), 4}. However, all patients with stage IC(capsule rupture) (n=17) were alive without recurrence. Collectively, there was no significant difference in the overall survival between the stage IA and IC groups (P=0.256). Moreover, there was no significant difference in DFS and OS between patients with stage IC(capsule rupture) and those with stage IA. In contrast, DFS and OS of the patients with stage IC(surface involvement/positive cytology) were poorer than those of patients with stage IA {OS; P=0.030, and DFS; P=0.005, respectively}. Thirteen pregnancies were observed in 9 patients. CONCLUSIONS: FSS may be considered a treatment option in women with stage I EOC, even in those with stage IC(capsule rupture) or more wishing to bear children.

RESUMO

AIM: To determine the efficacy of preoperative concurrent chemoradiation therapy (CCRT) to improve the prognosis of locally advanced adenocarcinoma of the uterine cervix. METHODS: Twenty-five patients with clinical stage IB2-IVB adenocarcinoma of the cervix were received preoperative CCRT. The CCRT protocol included: external radiotherapy to the pelvis: 39.6 Gy; intra-arterial or intravenous infusion of 70 mg/m2 cisplatin, days 1 and 22; 24-h continuous intravenous infusion of 700 mg/m2 5-FU, days 1-4 and 22-25. Two weeks after the end of CCRT, patients underwent restaging followed by appropriate surgery with pelvic lymphadenectomy. RESULTS: The overall clinical response rate was 96% (24/25), with a complete response (CR) in 12/25 patients and partial response (PR) in 12/25. On pathological examination, 5 of 19 patients (26%) undergoing surgery showed a pathological CR, 13 patients showed a PR, and 1 patient no change (NC) in their disease. Grade 3 or 4 hematological toxicity was observed in 15 patients. Grade 3 gastrointestinal toxicity was observed in 8 patients. The median follow-up period was 34 months (range, 6-69). The 5-year overall survival (OS) rate was 84%, and the progression-free survival (PFS) rate was 76%. CONCLUSIONS: Preoperative CCRT improves the survival of patients with locally advanced adenocarcinoma of the cervix, with manageable toxicities.

RESUMO

BACKGROUND: To estimate the survival impact of systemic retroperitoneal lymphadenectomy in patients diagnosed with International Federation of Gynecology and Obstetrics pTI-IIb clear cell carcinoma of the ovary (CCC). PATIENTS AND METHODS: Demographic and clinicopathologic data were obtained from the Tokai Ovarian Tumor Study Group between 1986 and 2006. Survival curves were calculated using the Kaplan-Meier method. Differences in survival rates were analyzed using the log-rank test. RESULTS: A total of 205 patients had clinical pTI-IIb CCC (median age: 52 years, range: 30-75). One hundred and four (50.7%) patients underwent systemic retroperitoneal lymphadenectomy. Lymphadenectomy was not associated with improved disease-free and overall survival in all patients (P = 0.353 and P = 0.645, respectively). Moreover, lymphadenectomy did not improve the overall survival in those with pTIc CCC (P = 0.433). Similarly, on univariate analysis, age, volume of ascites, preoperative CA 125 values, and regimen of chemotherapy were not significant factors. In addition, there was no significant difference in the ratio of positive lymph node metastases regardless of the completion of lymphadenectomy (P = 0.955). CONCLUSION: Our data suggest that patients with pTI-IIb CCC who underwent lymphadenectomy did not show a significant improvement in survival. There was no significant difference in the overall and disease-free survival rates in pTI-IIb CCC patients regardless of the completion of surgical staging lymphadenectomy.

RESUMO

BACKGROUND: Twist, a basic helix--loop-helix transcription factor, has been reported to be associated with the development and progression of human cancer. We examined the distribution and expression of Twist in cervical cancer to examine its clinical significance. PATIENTS AND METHODS: We examined the distribution and expression of Twist in 101 cervical cancer specimens and determined the association between their expression and the clinico-pathological features observed, including patient outcome. RESULTS: Of the 101 specimens, 55 cases were negative for Twist immuno-expression, whereas 46 were positive. When categorized into negative versus positive expression, Twist was not associated with any of the clinico-pathological parameters examined. Positive Twist expression significantly predicted poorer overall survival (OS) and progression-free survival (PFS) when compared with negative expression (P < 0.01). In the multivariate analyses, positive Twist expression was an independent prognostic factor for OS (P < 0.05). CONCLUSIONS: Our data imply that positive Twist expression seems to be a useful marker in patients with cervical cancer likely to have an unfavorable clinical outcome.

RESUMO

N-acetylglucosaminyltransferase V (GnT-V) is an enzyme that catalyses beta1-6 branching of N-acetylglucosamine on asparagine-linked oligosaccharides of cell proteins. The present study aimed to investigate GnT-V expression and its prognostic significance in endometrial cancer. N-acetylglucosaminyltransferase V expression was studied by immunohistochemistry in 74 surgically resected endometrial cancers, and the staining intensity was evaluated. High GnT-V expression in tumour cells was found in 43 (58.1%) of the 74 cases, and was positively correlated with advanced patient age, histological grade, and lymph vascular space involvement. Patients with high GnT-V expression had significantly impaired overall survival and progression-free survival (PFS) (P=0.0041 and P=0.0023, respectively) compared to patients with low expression of GnT-V. On multivariate analysis, GnT-V expression was an independent prognostic factor for PFS (P=0.0364). beta1-6 branching of asparagine-linked oligosaccharides was also detected in GnT-V-positive endometrial cancer cells by leukoagglutinating phytohaemagglutinin (L(4)-PHA) staining, and the molecular size of the major glycoproteins recognised by L(4)-PHA was approximately 60-200 kDa by lectin blot analysis. These results suggested that high GnT-V expression was correlated with an unfavourable clinical outcome, and that GnT-V is involved in the malignant potential of endometrial cancer by increasing the synthesis of beta1-6 branching of asparagine-linked oligosaccharides.

RESUMO

Nongestational pure choriocarcinoma of the ovary is a very rare germ cell tumor. Except in women before menarche, determination of the origin is very difficult without genetic analysis. We present a pure nongestational choriocarcinoma arising in the left ovary of a 19-year-old woman. Following surgery, pathologic findings of the tumor demonstrated pure choriocarcinoma without combination of other germ cell tumor elements. We confirmed its nongestational origin by DNA polymorphism analysis at 15 short tandem repeat loci. Multiple courses of chemotherapy with methotrexate, etoposide, and actinomycin-D were effective for this case. DNA polymorphism analysis is useful to determine genetic origin in pure choriocarcinoma of the ovary.

RESUMO

Twist is a transcription factor that regulates the expression of tumour suppressors such as E-cadherin. We examined the distribution and expression of Twist in human epithelial ovarian carcinoma (EOC) to examine its clinical significance. Paraffin sections from EOC tissues (n=82) were immunostained with Twist antibody, and the staining intensity was evaluated. The clinicopathological factors examined were age, International Federation of Gynecology and Obstetrics staging, histological type, tumour grade, preoperative value of CA125, peritoneal cytology, volume of ascites and residual tumour after cytoreductive surgery. Overall survival (OS) and progression-free survival (PFS) were evaluated using the Kaplan-Meier method, and multivariate analysis was performed using the Cox proportional hazard analysis. Of the 82 carcinomas, 49 (59.8%) cases were negative for Twist immunoexpression, and 33 (40.2%) were positive immunoexpression. When categorized into negative vs positive expression, Twist was not associated with any of the clinicopathological parameters examined. However, positive Twist expression significantly predicted poorer OS and PFS when compared with negative expression (P<0.0001). In the multivariate analyses, positive Twist expression was the only independent prognostic factor for survival in this study (P<0.0001). Positive Twist expression seems to be a useful marker in patients with EOC likely to have an unfavourable clinical outcome.

RESUMO

Indoleamine 2,3-dioxygenase (IDO) is a tryptophan-catabolising enzyme inducing immune tolerance. The present study aimed to investigate IDO expression and its prognostic significance in endometrial cancer. Indoleamine 2,3-dioxygenase expression in endometrial cancer tissues (n = 80) was immunohistochemically scored as four groups (IDO-, 1+, 2+, and 3+). The high IDO expression (IDO2+ or 3+) in tumour cells was found in 37 (46.3%) of the 80 cases, and was positively correlated with surgical stage, myometrial invasion, lymph-vascular space involvement, and lymph node metastasis, but not with the histological grade. Patients with high IDO expression had significantly impaired overall survival and progression-free survival (PFS) (P = 0.002 and P = 0.001, respectively) compared to patients with no or weak expression of IDO (IDO- or 1+). The 5-year PFS for IDO-/1+, 2+, and 3+ were 97.7, 72.9, and 36.4%, respectively. Even in patients with early-stage disease (International Federation of Gynecology and Obstetrics I/II, n = 64), the PFS for IDO2+/3+ was significantly poor (P = 0.001) compared to that for IDO-/1+. On multivariate analysis, IDO expression was an independent prognostic factor for PFS (P = 0.020). These results indicated that the high IDO expression was involved in the progression of endometrial cancer and correlated with the impaired clinical outcome, suggesting that IDO is a novel and reliable prognostic indicator for endometrial cancer.

RESUMO

Angiotensin II, a main effector peptide in the renin-angiotensin system, acts as a growth-promoting and angiogenic factor via type 1 angiotensin II receptors (AT(1)R). We have recently demonstrated that angiotensin II enhanced tumour cell invasion and vascular endothelial growth factor (VEGF) secretion via AT1R in ovarian cancer cell lines in vitro. The aim of the present study was to determine whether AT1R expression in ovarian cancer is correlated with clinicopathological parameters, angiogenic factors and patient survival. Immunohistochemical staining for AT1R, VEGF, CD34 and proliferating cell nuclear antigen (PCNA) were analysed in ovarian cancer tissues (n = 67). Intratumour microvessel density (MVD) was analysed by counting the CD34-positive endothelial cells. Type 1 angiotensin II receptors were expressed in 85% of the cases examined, of which 55% were strongly positive. Type 1 angiotensin II receptors expression was positively correlated with VEGF expression intensity and MVD, but not with histological subtype, grade, FIGO stage or PCNA labelling index. In patients who had positive staining for AT1R, the overall survival and progression-free survival were significantly poor (P = 0.041 and 0.017, respectively) as compared to those in patients who had negative staining for AT1R, although VEGF, but not AT1R, was an independent prognostic factor on multivariate analysis. These results demonstrated that AT1R correlated with tumour angiogenesis and poor patient outcome in ovarian cancer, suggesting its clinical potential for a novel molecular target in strategies for ovarian cancer treatment.

RESUMO

While angiotensin II (Ang II) has been shown to inhibit migration of extravillous trophoblasts via plasminogen activator inhibitor-1 (PAI-1) activation, it has remained unclear whether it stimulates or inhibits malignant behavior of choriocarcinoma cells. Since we previously found an involvement of the renin-angiotensin system (RAS) in the proliferative potential in choriocarcinoma cells (BeWo), mediated via the Ang II type 1 receptor (AT1R), in the present study we investigated the effects of Ang II on choriocarcinoma cell migration/invasion in vitro using Transwell cell culture chambers. Ang II (10(-8)M) promoted migration and invasion by a choriocarcinoma cell line and augmented random cell mobility on checkerboard analysis. Immunoblotting showed Ang II to activate the phosphorylation of FAK and Akt in BeWo cells. Furthermore Ang II effects on cell migration were abolished by a selective AT1R antagonist and a phosphatidylinositol 3-kinase (PI3K) inhibitor. The present results suggest that Ang II-induced migration and invasion of choriocarcinoma cells probably involves PI3K following binding to the AT1R.

RESUMO

OBJECTIVE: Rheumatoid arthritis is a chronic inflammatory autoimmune disease with proinflammatory cytokines involved in its pathogenesis. Recently in vitro as well as in vivo studies have shown that iloprost, a stable prostacyclin analogue, can reduce the release of these cytokines. This study was performed to further investigate the anti-inflammatory effects of iloprost by determining plasma adhesion molecules as markers of endothelial cell activation, and plasma thrombomodulin as a parameter of endothelial cell injury in patients with rheumatoid arthritis receiving oral iloprost therapy. METHODS: Plasma thrombomodulin levels and the values of the plasma adhesion molecules VCAM-1 (vascular cell adhesion molecule 1), E-selectin (CD62E), and ICAM-1 (intercellular adhesion molecule 1, CD 54) were measured by ELISA during a 7-day period of treatment with orally-administered iloprost in 14 patients with active rheumatoid arthritis. Finally, the same parameters were determined at the end of the observation period (1 week after the end of therapy). In addition, the disease activity was measured using the DAS (disease activity score) as well as the patients' self-assessed pain severity, and correlated with the changes of plasma adhesion molecule and thrombomodulin levels. RESULTS: The plasma levels of all three adhesion molecules as well as of thrombomodulin significantly decreased under therapy with oral iloprost. After 1 week (day 7 of therapy), the mean percent changes from day 0 were -20.1% for VCAM-1 (p = 0.008), -21.2 for ICAM-1 (p = 0.003), -24.6% for E-selectin (p = 0.001), and -21.7% for thrombomodulin (p = 0.003). This decrease lasted up to 1 week after the end of therapy in the case of VCAM-1 (p = 0.023) and ICAM-1 (p = 0.001). Further analysis of the results revealed additional significant correlations between different parameters of clinical disease activity, thrombomodulin and adhesion molecules. CONCLUSION: This study showed hints towards clinical effects in patients with rheumatoid arthritis receiving oral iloprost therapy. Pathophysiologically, the decrease of adhesion molecules points at an immunomodulating effect of iloprost. The observed thrombomodulin-lowering effect of iloprost may indicate stabilisation of endothelial cell function by diminishing endothelial cell injury.

RESUMO

The transcriptional factor Ikaros was originally found to function as a key regulator of lymphocyte differentiation. In addition, we have reported that Ikaros regulates the human placental leucine aminopeptidase (P-LAP)/insulin-regulated aminopeptidase (IRAP) gene in choriocarcinoma trophoblastic cells, suggesting that Ikaros might be involved in placental development, while even its presence in human placenta remains undetermined. We therefore sought to clarify the location and roles of Ikaros in human placenta. Immunohistochemical analysis showed modest Ikaris expression in syncytium, and intense expression in extravillous trophoblasts (EVTs) in first trimester placenta. Western blot analysis showed that villous trophoblasts principally expressed Ikaros-2/3, while Ikaros-x (Ikx) was predominantly expressed in cultured EVTs. Furthermore, to investigate the functional role of Ikx in EVTs, the EVT cell line HTR-8/SVneo was infected with a retrovirus vector expressing the hemagglutinin (HA)-tagged dominant negative isoform Ikaros-6 (Ik6), which prevents the DNA-binding activity of Ikx. Antibody against HA showed successful transduction of Ik6 in HTR-8/SVneo cells on immunocytochemistry and Western blotting. Transduction of Ik6 significantly reduced the migratory and invasive abilities of HTR-8/SVneo cells. These results suggest that Ikx is involved in migration and invasion of EVTs in early placentation.
